Great check valves
Install is quick and easy without any hot work. So far they are quiet with no chatter or hammer noise.

I would buy again
Worked as expected. This product was supposed to be next day delivery to upstate NY but took over a week to get because the shipping company delivered to Upstate NY by way of Houston TX from NJ. This was not Supply House's fault. They found it for me and said I would have it next day, and I did.
